Beschreibung
Zusammenfassung:The plug (10) has a connection pin (14) arranged in a plug housing (12). A heating coil (24) is electrically contacted with the connection pin. The heating coil is arranged in a glow chamber (16) that is sealed by a gas-tight sealing (28) made of glass or ceramic material e.g. borosilicate glass or zinc-glass or magnesium or aluminum. The gas-tight sealing is provided with an auxiliary disk (26) designed as a polymer ring. The glow chamber is made of reactive calcium, magnesium and aluminum-content alloy powders. Die Erfindung bezieht sich auf eine elektrisch beheizbare Glühkerze (10) mit einem Kerzengehäuse (12) und einem daran aufgenommenen Anschlussbolzen (14). Mit diesem ist eine Heizwendel (24) elektrisch kontaktiert, die in einer Glühkammer (16) aufgenommen ist. Die Glühkammer (16) ist durch eine gasdichte Abdichtung (28) aus einem geschmolzenen Glas- oder Glaskeramikmaterial (30, 32, 36) abgedichtet.
